Answer 1

Answer:

5x2-8x=4

5x2-8x-4=0

5x2-10x+2x-4

5x(x-2)+2(x-2)

5x+2=0,x-2=0

x=-2/5,x=2

Roots are -2/5,2

Step-by-step explanation:

I hope this answer may help you

Answer 2

Step-by-step explanation:

By factorisation method:

5x²-8x-4=0

5x²-10x+2x-4=0

5x(x-2)+2(x-2)=0

(x-2)(5x+2)=0

x-2=0

x=2.

5x+2=0

x=-2/5.

2 and -2/5 are the roots of the quadratic equation 5x²-8x-4.
